RESUMO

CONTEXT: Over the past several decades, orthopedic surgery has seen a substantial increase in the number of surgeons completing fellowship training. Doctors of Osteopathic Medicine (DOs) continue to advance their orthopedic education through subspecialty fellowship training. DOs have represented between approximately 6 % and 15 % of American Orthopaedic Foot and Ankle Society (AOFAS) fellows. Although historical representation has been considered strong, the fellowship match years 2020 and 2021 have seen a decline in osteopathic orthopedic surgeons participating in foot and ankle fellowships. This deviates from the recent trends of increasing participation across orthopedic subspecialities. OBJECTIVES: To investigate and review the trends of orthopedic foot and ankle fellowship training. METHODS: Data was reviewed from the AOFAS regarding number of fellows matched and degree obtained. Data from the Federation of State Medical Boards (FSMB), American Orthopaedic Foot and Ankle Society (AOFAS) and Association of American Medical Colleges (AAMC) were reviewed for physician trends and match statistics. RESULTS: Fellowship match years 2020 and 2021 have seen a decline in osteopathic orthopedic surgeons participating in foot and ankle fellowships, with only roughly 3% of AOFAS fellows being osteopathic trained. CONCLUSIONS: Orthopedic surgery has the highest rate of subspecialty training of all surgical specialties. Although there is hope for an increasing osteopathic presence in orthopedic surgery, recent literature has pointed to potential for continued bias in opportunities for osteopathic students. We hope that increased participation of osteopathic graduates in orthopedic surgery training programs will result in the continued expansion of osteopathic orthopedic surgeons completing fellowship training, including in foot and ankle surgery.

RESUMO

The purpose of this study is to evaluate trends in distal clavicle excision (DCE) in association with arthroscopic rotator cuff repair (RCR) from 2010 to 2019. The National Surgical Quality Improvement Program database was queried to identify all patients who underwent arthroscopic RCR from January 1, 2010 to December 31, 2019, and was further subdivided into procedure type: (1) isolated RCR; and (2) RCR with arthroscopic or open DCE. The proportion of each surgery type, by year and within groups, was calculated. The Cochran-Armitage test for trend was used to analyze yearly proportions of RCR with concomitant DCE. In a sample size of 19,163 patients, the proportion of RCR with DCE decreased from 51.2% to 40.8% (r = -0.830; p = 0.003). Although the results of this study suggest that surgeons are performing fewer DCEs in the setting of RCR, many DCEs are still being done.

RESUMO

BACKGROUND: The purpose of this study was to identify demographics and risk factors associated with unplanned 30-day readmission and reoperation following open procedures for shoulder instability and examine recent trends in open shoulder instability procedures. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried using current procedural terminology (CPT) codes 23455, 23460, and 23462 to find patients who underwent shoulder instability surgery from 2015 to 2019. Independent sample Student t-tests and chi-square tests were used in univariate analyses to identify demographic, lifestyle, and perioperative variables related to 30-day readmission following repair for shoulder instability. Multivariate logistic regression modeling was subsequently performed. RESULTS: In total, 1,942 cases of open surgical procedures for shoulder instability were identified. Within our study sample, 1.27% of patients were readmitted within 30 days of surgery, and 0.85% required reoperation. Multivariate logistic regression modeling confirmed that the following patient variables were associated with a statistically significant increase in the odds of readmission: open anterior bone block/Latarjet-Bristow procedure, being a current smoker, and a long hospital stay (all P<0.05). Multivariate logistic regression modeling confirmed statistically significant increased odds of reoperation with an open anterior bone block or Latarjet-Bristow procedure (P<0.05). CONCLUSIONS: Unplanned 30-day readmission and reoperation after open shoulder instability surgery is infrequent. Patients who are current smokers, have an open anterior bone block or Latarjet-Bristow procedure, or a longer than average hospital stay have higher odds of readmission than others. Patients who undergo an open anterior bone block or Latarjet-Bristow procedure have higher odds of reoperation than those who undergo an open soft-tissue procedure. Level of evidence: III.

RESUMO

Introduction  Rotator cuff repair (RCR) procedures are some of the most common orthopaedic surgeries performed in the United States. Compared to other orthopaedic procedures, RCRs are of relatively low morbidity. However, complications may arise that result in readmission to an inpatient healthcare facility. The purpose of this study is to identify the demographics and risk factors associated with unplanned 30-day readmission after RCR. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent elective RCR from 2015-2019. Univariate and multivariate analyses were utilized to assess patient demographics, comorbidities, and peri-operative variables predicting unplanned 30-day readmission. Results Of the identified 45,548 patients that underwent RCR, 597 (1.3%) required readmission within 30 days of the procedure. Multivariate analysis identified male sex (OR 1.36, 95% CI: 1.10, 1.67), hypertension (OR 1.29, 95% CI:1.03, 1.62), chronic obstructive pulmonary disease (COPD) (OR 2.07, 95% CI: 1.46, 2.93), American Society of Anesthesiologists (ASA) Class III (OR 1.85, 95% CI: 1.07, 3.18), ASA Class IV (OR 5.38, 95% CI: 2.70, 10.72), and total operative time (OR 1.002, 95% CI: 1.000, 1.004) as independent risk factors for unplanned readmission. Conclusion Unplanned 30-day readmission after RCR is infrequent. However, certain patients may be at increased risk for unplanned 30-day admission to an inpatient facility. This study confirmed male sex, COPD, hypertension, ASA Class III, ASA Class IV, and total operative time to be independent risk factors for readmission following outpatient RCR.

RESUMO

BACKGROUND: Shoulder instability procedures have low morbidity; however, complications can arise that result in readmission to an inpatient healthcare facility. The purpose of this study is to identify the demographics and risk factors associated with unplanned 30-day readmission and reoperation following arthroscopic and open treatment for shoulder instability. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried to find patients who underwent shoulder instability surgery from 2015 to 2019. Independent sample Student t-tests, chi-square, and (where appropriate) Fisher's exact tests were used in univariate analyses to identify demographic, lifestyle, and perioperative variables related to 30-day readmission and reoperation following repair for shoulder instability. Multivariate logistic regression modeling was subsequently performed. RESULTS: Of the 11,230 cases included in our sample, only 0.54% were readmitted, and 0.23% underwent reoperation within the 30-day postoperative period. Multivariate logistic regression modeling confirmed that the following patient variables were associated with statistically significantly increased odds of readmission and reoperation: open repair, congestive heart failure (CHF), and hospital length of stay. CONCLUSIONS: Unplanned 30-day readmission and reoperation after shoulder instability surgery is infrequent. Patients with American Society of Anesthesiologists class II, CHF, longer than average hospital length of stay, or an open procedure have higher odds of readmission than patients without those factors. Patients who have CHF, longer than average hospital length of stay, and open surgery have higher odds of reoperation than others. Arthroscopic procedures should be used to manage shoulder instability, if possible.

RESUMO

Fourth-year away rotations are well recognized as an important modifiable variable that has been shown to increase a student's opportunity to match into orthopaedic surgery. The purpose of this article was to determine whether allopathic (MD) and osteopathic (DO) medical students have equal opportunities for away rotations in terms of (1) eligibility and (2) fees associated with rotations after the single accreditation merger. Methods: A cross-sectional study was performed during the 2021 application cycle (April to November) by reviewing all nonmilitary, Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery programs (n = 194). Each program's website, affiliated school of medicine's website, and visiting student applications service portal were searched. Eligibility criteria for an away rotation and associated fees were recorded. Results: Of the 194 programs, 18 (9.3%) of programs were found to have publicly published eligibility for away rotations that prohibited students based on applicant degree. Five (2.6%) programs/medical schools had fees that were larger for DO medical students compared with MD medical students ranging for $50 to $5,000. No programs/medical schools had larger fees for MD medical students compared with DO medical students. Conclusions: Although DO and MD degrees are equivalent degrees for licensing and credentialing and graduate medical education has transitioned to a single accrediting body, there remained discord in the opportunities for fourth-year away rotations between osteopathic and allopathic medical students. This study highlights the necessity for greater reform, consistency, and transparency among orthopaedic surgery residency programs and their affiliated institutions.

RESUMO

INTRODUCTION: Orthopaedic trauma surgeons have an intricate relationship with the medical device industry. In the past decade, legislation has created transparency of monetary exchanges between physicians and industry. In 2013, the Physician Payments Sunshine Act was passed and ultimately led to the creation of the Open Payments Database. The purpose of this study was to evaluate trends in industry payments to orthopaedic trauma surgeons. METHODS: A retrospective review of the Centers for Medicare & Medicaid Services' Open Payments Database was conducted for general industry payments to orthopaedic trauma surgeons from 2014 to 2019. Total payments and subtype payments were analyzed for yearly trends. All payments were converted to 2019 US dollars to adjust for inflation. Descriptive statistics included analysis of payments, number of surgeons, types of payments, top contributing companies, and regional comparisons. Trends were assessed through the Jonckheere-Terpstra test. Statistical significance was defined at P < 0.05. RESULTS: From 2014 to 2019, 45,312 individual payments were given to orthopaedic trauma surgeons (N = 3208) accounting for a total of $41,376,397.85 (USD), with a mean of $919.54 per payment. Increased trends were noted for median annual payments, number of payments, and number of surgeons receiving payments. Compared with 2014 ($460.91), median payments were increased by 90.9% in 2016 ($879.85), 102.6% in 2018 ($933.81), and 178.6% in 2019 ($1284.06). Payment subtypes that demonstrated increasing median payments included consulting fees (P = 0.028); education (P < 0.001); entertainment, food, and beverage (P < 0.001); and travel (P = 0.019). Decreases in median payments were seen in royalties (P = 0.044) and grant funding (P < 0.001). Regional comparisons demonstrated increasing trends in median payments in the midwest (P = 0.011), south (P < 0.001), and west (P = 0.003), but not in the northeast (P = 0.081). DISCUSSION: In our study, we found that industry payments to orthopaedic trauma surgeons were increasing markedly between 2014 and 2019, particularly among consulting fees, education, entertainment, food and beverage, and travel.

RESUMO

BACKGROUND: In recent time, there has been an increased push toward transparency in industry funding toward physicians. The Physician Payments Sunshine Act called for the creation of the Open Payments Database managed by the Centers for Medicare & Medicaid Services. To our knowledge, there have been no studies evaluating the trends in payments among adult reconstruction fellowship-trained orthopedic surgeons. The purpose of this study is to investigate trends in all payments to adult reconstruction-trained orthopedic surgeons from 2014 to 2019. Secondary outcomes included evaluating trends in yearly subpayment categories, regional variations, as well as characterizing the top 5 industry companies. METHODS: A review of the Centers for Medicare & Medicaid Services Open Payments Database was performed to identify all payments to adult reconstruction-trained orthopedic surgeons. A total of 94,265 payments were made to 4911 surgeons accounting for a total of $258,865,231.20 during the study period. Our primary outcome was to assess the trend in median payment per year to individual surgeons. Secondary outcomes included evaluating payment trends with respect to subtype, location as defined by United States Census regions, as well as specifics concerning the top 5 companies. RESULTS: Over the study period, there was a nonsignificant increasing trend in median payment per surgeon (r = 0.49, P = .096). However, there was also a significantly increasing trend in the number of payments per year (r = 0.83, P = .014), as well as the number of surgeons receiving payments (r = 0.88, P = .019). With respect to subcategory payments, there were significantly increasing trends in the median payment per surgeon for education (1054%, r = 0.942, P < .001) and entertainment/food and beverage expenses (20.2%, r = 0.49, P = .020), as well as a significantly decreasing trend for median honoraria payments per surgeon (20.2%, r = -0.04, P = .005). No significant regional trends were identified. Of the top 5 companies, one demonstrated a significantly decreasing trend in median payment per surgeon (21.6%, r = -0.109, P < .001), whereas the others remained unchanged. CONCLUSION: In this study, we found a nonsignificant increasing trend in payments to adult reconstruction-trained surgeons as well as an increasing number of surgeons receiving payments. There were increasing trends in median payment per surgeon for education and entertainment expenses, but a decreasing trend for honoraria payments. No significant regional trends were identified. The majority of the top 5 companies had nonsignificant trends in their payments. Further studies are needed to characterize the disclosure of payments and the impact of industry payments on clinical outcomes. LEVEL OF EVIDENCE: IV.

RESUMO

INTRODUCTION: The Physician Payments Sunshine Act was placed into law in 2010 in an effort to create transparency between physicians and industry. Along with many other specialties, orthopaedic surgeons have long worked intimately with medical industry companies. This study aimed to evaluate trends in industry payments to general orthopaedic surgeons from 2014 to 2019. METHODS: A retrospective review of the Center of Medicare and Medicaid Services' Open Payments Database was done to identify all industry payments to all general orthopaedic surgeons (ie, not subspecialty affiliated) from 2014 to 2019. The researchers analyzed total payments and subtype payments for yearly trends, and a regional analysis was done. The primary outcome was the overall trend in total median payments, which was assessed through the Jonckheere-Terpstra test. Descriptive statistics include medians with interquartile ranges. P < 0.05 was considered statistically significant. RESULTS: Between 2014 and 2019, a total of 1,330,543 payments totaling $1.79 billion dollars was paid to 108,041 general orthopaedic surgeons. During this time, the number of surgeons receiving payments increased with a significant uptrend in median payments per surgeon (P < 0.001; Table 1). The top 25% percentile of general orthopaedic surgeons received >95% of payments, whereas the bottom 25% received <0.1%. The general payment types all saw significant increases (P < 0.001) between 2014 and 2019, with the exception of "Ownership or Investment Interests" (P = 0.657) and "Royalty or License" (P = 0.517). Significant regional uptrends in median industry payments were also seen in the Midwest, Northeast, South, and West (P < 0.001). Four of the top five orthopaedic industry companies made payment increases between 2014 and 2019. CONCLUSION: Industry payments to general orthopaedic surgeons between 2014 and 2019 have increased with a considerable disparity in payments among the top-paid orthopaedic surgeons.

RESUMO

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction before 18 years of age has been linked with an increased risk for failure when the graft diameter is <8 mm. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether autologous hamstring graft size can be reliably predicted with the use of preoperative magnetic resonance imaging (MRI) measurements. We hypothesized that the average of multiple axial cross-sectional area MRI measurements for the semitendinosus tendon and gracilis tendon would alone accurately predict graft diameter. Additionally, factoring in specific demographic data to the MRI cross-sectional areas would provide a synergistic effect to the accuracy of graft diameter predictions. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: We retrospectively reviewed 51 pediatric patients undergoing ACL reconstructions (age <18 years) performed using either a quadruple-strand semitendinosus tendon or combined double-bundle semitendinosus tendon-gracilis tendon autograft. Preoperative axial MRI scans at multiple points along the craniocaudal axis-specifically, at the level of the joint line, 3 cm cephalad to the medial tibial plateau, and 5 cm cephalad to the medial tibial plateau-were used to determine the combined cross-sectional area of the semitendinosus and gracilis tendons. The MRI measurements were analyzed using Pearson correlation as well as regression analysis to evaluate strength of correlation between measurements. Binomial linear regression was used to analyze the same predictive variables assessed by multiple regression. RESULTS: The predicted graft diameter was within 0.5 mm of the intraoperative graft size in 37 of 51 (72.5%) patients and within 1 mm of the intraoperative graft size in 49 of 51 (96.1%). With the addition of demographics, the accuracy of predictions increased to 78.4% within 0.5 mm and 98% within 1 mm of the actual graft size. Additionally, 38 of 42 patients whose true graft diameter was ≥8 mm were correctly classified, giving a sensitivity of 90.4%. For those whose true graft diameter was <8 mm, 8 of 9 patients were correctly classified; therefore, the specificity was 88.9%. CONCLUSION: The results of our study suggest that taking the average of multiple preoperative MRI measurements can be used to accurately predict autologous hamstring graft size when approaching pediatric patients undergoing ACL reconstruction.

RESUMO

PURPOSE: The purpose of the present study is to investigate trends in overall payments to orthopaedic sports medicine surgeons reported by the Open Payments Database (OPD) over the 6 full years of available data (2014-2019). METHODS: A retrospective review of industry payments to United States sports medicine trained orthopaedic surgeons from 2014 to 2019 was performed using the Centers for Medicare and Medicaid Services OPD. Total payments and subtype payments were analyzed for yearly trends. Regional analysis was also performed. The primary outcome was the overall trend in total median payments (defined as the median total payments per surgeon per year), which was assessed via the Jonckheere-Terpstra test. Descriptive statistics include medians with interquartile ranges. P values < .05 were considered statistically significant. RESULTS: From 2014 to 2019, there were a total of 1,941,772 payments to 12,816 sports medicine orthopaedic surgeons. The median payments to surgeons demonstrated a significant upward trend (P < .001). The total number of payments (r = 0.002; P = .99) did not significantly correlate with changing year. The top 5 compensated surgeons received 45.8% of all industry contributions with a median total payment of $9,210,974.06 (interquartile range: 25,029,951.46). The majority of industry contributions in the top 5 earners were attributed to royalties and licenses (98.7%). Across the study period, 89.4% of the total orthopaedic sports medicine surgeons received a yearly total payment less than $10,000, which made up 8.3% of the total industry payment sum. Those receiving a yearly total payment greater than $500,000 accounted for 0.3% of surgeons but received 53.4% of the sum payments. We found a yearly increasing trend in payments in all regions including the Midwest, South, Northeast, and West (P < .001, P < .001, P < .001, and P = .006). CONCLUSION: Despite the transparency of reporting mandated by the Sunshine Act, orthopaedic sports medicine surgeons have continued to maintain industry relationships with a notable disparity in distribution. CLINICAL SIGNIFICANCE: Our analysis suggests continued relationships among sports medicine surgeons and industry. Future research is needed to determine how this impacts medical practice in the United States.

RESUMO

BACKGROUND: The chondroprotective effect and secondary stabilizing role of the meniscus has been well-established. Meniscal preservation during anterior cruciate ligament reconstruction (ACLR) has been advocated in the literature and supported by advancements in surgical techniques. PURPOSE: To examine the recent trends in concomitant partial meniscectomy and meniscal repair procedures with ACLR. STUDY DESIGN: Descriptive epidemiological study. METHODS: Patients who underwent arthroscopic meniscectomy (Current Procedural Terminology [CPT] codes 29880, 29881), meniscal repair (CPT codes 29882, 29883), and ACLR (CPT code 29888) between 2010 and 2018 were identified using the National Surgical Quality Improvement Program database. We calculated the proportion of patients who underwent each surgery type, stratified by year and by patient age and body mass index (BMI) groups. The Cochran-Armitage test for trend was used to analyze yearly proportions of concomitant meniscal surgery types. RESULTS: During the 9-year study period, 22,760 patients underwent either isolated ACLR (n = 10,562) or ACLR with concomitant meniscal surgery (either meniscectomy [n = 8931] or meniscal repair [n = 3267]). There was a gradual decrease in the proportion of meniscectomies (from 80.8% of concomitant procedures in 2010 to 63.8% in 2018), while the proportion of meniscal repairs almost doubled (from 19.2% in 2010 to 36.2% in 2018) (trend, P < .001). ACLR with meniscal repair increased in patients aged 35 to 44 years and 45 to 54 years (trend, P = .027) between 2010 and 2018; at the same time, the proportion of normal weight patients decreased by 17.7%, the proportion of overweight patients increased by 13.2%, and increases were seen in BMI groups corresponding to obesity classes 1 to 3 (trend, P < .001). In 2010, the average BMI of patients undergoing ACLR with meniscectomy versus meniscal repair differed by 2 (P = .004), but by 2018 the difference was nonsignificant (28.83 ± 5.80 vs 28.53 ± 5.73; P = .113). CONCLUSION: Between 2010 and 2018, there was an upward trend in the proportion of meniscal repairs performed during ACLR, with notable increases in the proportion of repairs being performed on older, overweight, and obese patients.

RESUMO

INTRODUCTION: Anterior Cruciate Ligament Reconstructions (ACLR) are routinely performed in an outpatient setting with low 90-day readmission rates (2.3%); however, admissions rates in the immediate perioperative period have been previously reported as high as 13.1%. Despite the surprisingly high number of patients requiring immediate perioperative admission, there has been a lack of recent literature specifically examining the associated risk factors for admission. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, a query for patients who underwent ACLR from 2011 through 2018 was performed using Current Procedural Terminology codes. The following concomitant procedures were included: meniscectomy, meniscal repair, diagnostic arthroscopy, loose body removal, synovectomy, chondroplasty, abrasion chondroplasty, drilling for osteochondritis dissecans. Demographics including age, sex, race, body mass index (BMI) and comorbidities were collected. Perioperative factors collected were anesthesia type and operative times. Patient demographic and perioperative data were compared using Fisher's exact test and Pearson's chi-square test. Multivariate logistic regressions were used to calculate odds ratios (OR) and 95% confidence intervals (CI) of independent risk factors for postoperative admission. Holm-Bonferroni method yielded adjusted p-value thresholds for significance. RESULTS: Of the 20,819 patients undergoing ACLR with and without concomitant procedures, 3.8% of patients were admitted to the hospital in the immediate postoperative period. Following multivariate regression analysis, increased odds of admission were demonstrated with the use of regional anesthesia alone (OR = 2.77, 95%CI: 2.22-3.44; p < 0.001), increasing concurrent procedures (Table 1), and obesity classes II (OR = 1.62, 95%CI: 1.26-2.10; p < 0.001) and III (OR = 1.81, 95%CI: 1.33-2.47; p < 0.001). Subsequent subgroup analysis of the isolated ACLR procedures (N = 9,423) demonstrated a 3.3% postoperative admission rate. Multivariate regressions demonstrated increased odds of admission with regional anesthesia use only (OR = 2.62, 95%CI: 1.90-3.60; p < 0.001), obesity class II (OR = 2.22, 95%CI: 1.51-3.26; p < 0.001), and increasing minutes of operative time (OR = 1.01, 95%CI: 1.01-1.01; p < 0.001). Table 2 demonstrates increasing rates and odds of admission with increasing operative time in hours. CONCLUSION: Anterior Cruciate Ligament Reconstructions are routinely performed in an outpatient setting; nevertheless, a subset of ACLR patients is admitted postoperatively. We found an increased risk of admission with the use of regional anesthesia alone, increasing concurrent procedures and obesity classes II and III. A further understanding of patient risk factors for those undergoing ACLR allows orthopedic surgeons to better develop a preoperative plan and discuss patient expectations, which will lead to more efficient resource allocation and improved patient satisfaction.
